Application filed June 9, 1917. Serial No. 173,864.

To all whom it may concern:

Be it known that I, FREDERIC L. DEWEY, a citizen of the United States, and a resident of Canton, in the county of Fulton, State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had to the accompanying drawin s.

lhis invention relates to improvements in cultivators and particularly to that class of riding cultivators in which the wheels are adapted to be turned at an angle for guiding the machine, the turning of the wheels for directing the machine in one direction having the eflect of moving the shovel gangs relative to the frame in the same direction; and in which the wheels are adapted to be moved rearwardly relative to the frame when the shovel gangs are raised simultaneously for making the turn at the end of a row or for transportation of the machine from one point to another. It is the object of my invention to provide a new and improved form and arrangement of connections between the shovel gangs and the frame whereby the desired movements of the gangs may be attained with reat facility and with a minimum expen iture of force in the operation. It is another object of my invention to provide a new and improved form and arrangement of means for holding the shovel gangs in adjusted position laterally relative to each other whereby the distance between thegangs may be very readily regulated as may be desired. It is another object of my invention to provide a new and improved form and arrangement of framework which shall be particularly adapted to the requirements of a plow of this type and which shall also be capable of ready adjustment laterally for varying the distance between the carrying wheels. It is another object of my invention to improve cultivators in sundry details hereinafter pointed out. The preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specifically described. That which I believe to be new and desire to cover by this application is set forth in the claims.

In the drawings:

Figure 1 is a side View of a cultivator embodying the preferred form of my improved construction Fig. 2 is a top or plan view of the culti- Vator shown in Fig. 1;

Fig. 3 is a view similar to Fig. 1, but showing the parts in 'changed position, the gangs having been raised in unison with the consequent backward shifting of the carrying wheels;

Fig. 4 is a view similar to Fig. 2, but showing the gangs moved toward one side and the carrying wheels turned at an angle so as to carry the cultivator as a whole in the same direction;

Fig. 5 is an enlarged detail, being a fragmentary view at one ,side of the machine showing the construction of the arch of the frame of the cultivator;

Fig. 6 is an enlarged detail of the lever for adjusting the shovel gangs laterally relative to each other, being partly in section taken substantially on line 6-6 of Fig. 2;

Fig. 7 is an enlarged detail, being substantially a section taken on line 77 of Fig. 6;

Fig. 8 is an enlargeddetail, being substantially a section taken on line 8-8 of Fig. 4; and

Fig. 9 is an enlarged detail, being substantially a section taken on line 99 of Fig. 4.

Referring to the several figures of the drawings in all of which corresponding parts are indicated by the same reference characters, I

15 indicates the forward transversely-extending bar of the framework of the machine having fixedly connected thereto the side bars 1617 of the frame, the side bars 16-l7 being turned inward at their forward ends into engagement with the sides of a pole or tongue 18 whichvis fixedly connected at its rear end with the bar 15. At their rear ends the side bars l617 are fixedly connected by means of brackets 19 with the end portions of a transverselyextending pipe or bar 20, the brackets 19 comprising split sleeve portions as is shown in Figs. 1 and 3 for fixedly connecting them to the pipe 20. A seat 21 is supported in position from the main frame by means of bars 22-23 which are connected at their forward ends to the side bars 16-17 as is shown in Figs. 2 and 4, the bars 22-23 being supported in rear of their connection with the bars 16-17 by reason of their resting upon the cross-bar 20.

As will be understood from an inspection of Fig. 5, the cross-bar 20 comprises the major portion of the horizontally-extending bar of the main. frame arch, the arms of the arch being provided by means of angled bars 24-25, the horizontally-extending portions of which are revolubly mounted in the respective ends of the pipe or bar 20. The

horizontally-extending portions of the bars 2425 are revolubly and adjustably held in position in the ends of the pipe 20 by means of collars 26 adjustably. mounted in posit on upon said bars by means of set-screws 27,

the collars 26 being provided with fingers 28 the ends of whichare turned about ribs 29 forming parts of the brackets 19. By loosening the set-screws 27, the bars 24-25 can be adjusted laterally as may be desired, being secured revolubly 1n ad usted position by a subsequent tlghtenmg of the screws 27.

Carrying wheels 30-31 are mounted upon the framework by being journaled upon laterally-extending portions of axle members 32-33 respectively. The axle members 32-33 are mounted upon the main frame arch comprising the bars 20, 24 and 25 by means of sleeves 34 to which the axle members are fixedly secured by means of bolts passing through lugs 35 extending from said sleeves at one side. The sleeves 34 are j ournaled upon the vertically-extending portions of the bars 24-25, being held revolubly in position thereon by means of cotterpins 36 at their lower ends and spht collars 37 at their upper ends. The upper end portions of the axle members 32-33 are turned to extend forwardly, the front ends of the forwardly-extending arms being connected by means of a transversely-extending bar 38. The bar 38 is provided with a plurality of holes therethrough for the connection of the axle members 32-33 to provide for the lateral adjustment of the wheels 30-31 as has been above described. The verticallyextending portions of the axle members 32-33 are provided with inwardly-extending arms or foot levers 39-40, such foot levers being secured in position in the construction shown by means of eye-bolts 41 as is best shown in Fig. 5. As will be appreciated, the operator in position upon the. seat 21 is able by pressure upon one or the other of the foot levers 39-40 to swing both of the sleeves 34 about the vertically-extending portions of the.arms 24-25 for turning the wheels 30-31 at an angle relative to the framework for steering the machine toward either side as may be desired. By applying a preponderance of force to the foot lever at one side while at the same time applying sufiicient power to the foot lever at the opposite side for controlling the turning movement, the position of the wheels 30-31 may be regulated to a nicety.

The means for holding the arch members 24-25 and the carrying wheels 30-31 in adjusted position longitudinally of the machine comprises a rock-shaft 42 journaled in position across the main frame of the cultivator. The rock-shaft is held in adjusted position by means of a lever 43 fixedly mounted upon one end portion of the rock-shaft, the lever 43 being adjustable along a segmental rack 44 fixedly mounted in position upon the framework. The rock-shaft 42 is provided at its ends with downwardly-extending arms 45-46 fixedly mounted thereon, the lower ends of said arms being pivotally connected by rigid links 47-48, respectively, with the sleeves 34 carried by the vertically-extending arms of the main frame arch. When the lever 43 is given an upward movement from the position shown in Fig. 1 into the position shown in Fig. 3, the arms 45-46 are given a movement in clockwise direction in Figs. 1 and 3, serving through the medium of the links 47-48 to move the sleeves 34 backward, serving to carry the wheels 30-31 backward relative to the framework.

The means for mounting the shovels adjustably upon the frame of the machine comprises a transversely-extending bar 49 the ends of which are fixedly connected to brackets 50-51 as is clearly shown in Figs. 2 and4. The brackets 50-51 are provided with downwardly-extending arms 52-53, respectively, the lower ends of which are pivotally connected to links 54-55 which are pivotally connected at their upper ends to the frame-bar 15 as is clearly shown in Figs. 1 and'3. The brackets 50-51 are also provided with rearwardly-extending arms 56-57 fixedly connected thereto, the rear ends of the arms 56-57 being connected by means of eye-bolts 58 with the transverselyextending bar 38. By reason of the crossbar 49 being supported by the links 54-55 which are adapted to swing laterally, and by the arms 56-57 connected with the laterally-movable bar 38, it will be understood that the bar 49 is adapted to have a free and easy lateral movement with the bar 38, the arms 56-57 causing the bars 38 and 49 to move in unison.

Sleeves 59-60 slidably mounted upon the transversely-extending bar 49 are adjustable along said bar by the means hereinafter described. Each of the sleeves 59-60 is fixassesses edly connected in any appropriate manner with shovel bars 61-62 which are Provided with shovels 63 of any suitable type mounted thereon by any suitable means, the construction and arrangement being such that each of the gangs of shovels is adjustable vertically about the transversely-extending bar 49. The bars 62 at opposite sides of the plow are connected by links 64-65 with vertically-extending bars 66 which are connected attheir upper ends to the outer ends of a cross-bar 67 The means for swinging the shovel gangs about the bar 49 comprlses levers 68-69 revolubly mounted upon the rock-shaft 42, such levers being connected b means of links 70 with cross-bars 71 joining the bars 61-62 of the gangs. As is shown in Fig. 8, the lower ends of the ,links 7 0 pass through suitable openings in the bars 71, being provided with cotter pins 72 at their lower ends so as to prevent withdrawal of the links 70. Compression springs 73 about the link 70 bear at their lower ends upon the bars 71 and at their upper ends against collars 74 carried by the links 70. Thus upon a movement of the levers 68-69 in clockwise direction in Figs. 1 and 2, the shovel gangs are raised through the medium of the links 70. WVhen the levers 68-69 are held in lowered position as shown in Fig. 1, the gangs of shovels are held yieldingly also in lowered positim through the medium of the springs 73. The levers 68-69 are adapted to be adjustably connected with the rock-shaft 42 upon which they are revolubly mounted, this adjustable connection being effected through the medium of segmental racks 75-76 fixedly mounted upon the rock-shaft 42 adjacent to the levers 68-69, the levers being provided with latch mechanism of any approved type for adjustably engaging said segmental racks respectively.

By the construction above described, the gangs may be adjusted vertically through the medium of the levers 68-69 independently of each other, or they may be adjusted vertically in unison upon the turning of the rock-shaft 42 through the medium of the lever 43 as above described, the arrangement being such that the shovel gangs are raised as the wheels 30-31 are shifted backward and are again lowered when the wheels are moved forward to normal operative position. In order to assist in raising the gangs either separately or in unison, and to assist in the backward shifting of the wheels when the gangs are raised in unison, I have provided springs 77-78 connected at their rear ends to the lovers 68-69, respectively, and at their forward ends to the bar 15, the springs serving to exert a pull on the'levers for assistingin the gang-raising operation.

The means for adjusting the sleeves 59-60 laterally relative to each other along the bar 49 for adjusting the distance-between the shovel gangs comprises a bracket 79 revolubly mounted upon the bar 49, but held against movement longitudinally of said bar. The bracket 79 is provided at its free end portion with a sleeve 80 u on the ends of which a lever 81 is pivotally mounted, the lever being braced laterally by an arm 82 forming wlththe lever substantially a yoke construction. The bracket 79 has fixedly connected therewith a segmental rack 83 by which the lever 81 is adapted to be held in adjusted position relative to the bracket. The rack-bar 83 is supported by engagement with the rock-shaft 42, and the bracket 79 is prevented from moving upward out of position by a finger 84 preferably formed with-the bracket 79 and extending under the rock-shaft 42. It will be understood that the bracket 79 and the lever 81 and connected parts are adapted to move laterally with the bar 49 relative to the rock shaft 42. The lower ends of the arms of the yoke formed by the lever 81 and the arm 82 have revolubly mounted therein a transversely-extending sleeve 85 which is held against movement longitudinally of itself by the turned ends of pivotally mounted links 86-87 which extend through suitable openings in the ends of the sleeve 85, the links being prevented from withdrawal by cotter-pins 88. The links 86-87 extend forward from the sleeve 85 in diverging position, the outer ends of said links being pivotally connected with the sleeves 59-60, respectively, as is best shown in Fig. 9. When the transverse bar 38 is shifted laterally for turning the wheels at an angle, serving to carry the bar 49 and the shovel gangs laterally therewith, the bracket 79, the lever 81 and their coiiperating parts are moved laterally therewith. Whenever it is desired to adjust the distance between the shovel gangs, this is accomplished by a stroke of the lever 81 in one direction or the other, serving to vary the distance of the sleeve 85 from the bar 49 and serving thus through the diagonally-extending links 86-87 to adjust the sleeves 59-60 laterally relative to the bar 49. As will be readily understood, when the lever 81 is given a movement in clockwise direction in Figs. 1, 3 and 6 so as to carry the sleeve 85 away from the bar 49, the shovel gangs will be moved toward each other. When on the other hand the lever 81 is given a movement in counterclockwise direction in Fig. 6 so as to move the sleeve 85 toward the bar 49, the sleeves 59-60 and the shovel gangs carried thereby will be moved away from each other.

As will be leadily under stood, the bar 49, the brackets 50-51 fixedly connected thereto, and the arms 52-53 in turn fixedly connected to the brackets 50-51, constitute in effect a transversely-extending arch upon the crossbar of which the gangs are mounted. So far as I am aware, I am the first 1n the art to rovide a transversely-extending v arch with t 1e gangs mounted upon the crossbar of such arch, the arch being supported in position only by a single pair of swinging links such as the llnkS 54-55 and by connections to laterally-movable arms such as the forwardly-extending arms of the axlemembers 32-33 by which the carry1ng wheels are turned at an angle relatlve to the frame, and my claims are to be construed accordingly.
